Prosser and Rowe, fig. 203. 



This section begins about two miles east of Clarksville near Mr 

 Bradford Allen's about one quarter of a mile north of the Dela- 

 ware turnpike and ends at the top of Wolf hill nearly two miles 

 west of the village. The section comprises in descending order : 



Brownish arenaceous shales and sandstones in 

 upper part. The lower 200 feet or more of black 

 arenaceous shales which weather to a brownish 

 color, and brownish sandstones, are well ex- 

 posed in the several gullies of Wolf hill. The 

 upper part of the hill is mostly covered though 

 here and there ledges may bo seen. About 200 

 feet above the base of the formation fossils begin

 400 or 450 feet they become very abundant. The 

 fossils are as follows:
